Overview

The ABB SU201MR-K8 miniature circuit breaker (MCB) delivers precise branch circuit protection for industrial and commercial applications. Rated at 8A with a 10kA interrupting capacity per UL 489, this 1-pole device is optimized for 277V AC and 48V DC systems. The K-characteristic trip curve ensures rapid response to short circuits while minimizing nuisance tripping on sensitive loads like motors, transformers, and variable frequency drives. Designed for modular DIN rail mounting, the SU201MR-K8 features ring tongue terminals for secure, vibration-resistant wiring in control panels and distribution boards. With a power loss of 1.5W per pole at rated conditions, it maintains efficiency in compact installations. The turn-to-reset (RTT) actuator provides clear visual status indication and easy manual operation. Ideal for protecting lighting circuits, HVAC systems, and industrial automation, this MCB integrates seamlessly with ABB’s SU200MR series. Its 1P configuration optimizes space in tight installations without compromising performance. The device is part of ABB’s modular DIN rail product line, ensuring compatibility with standard industrial enclosures and distribution systems.
